This is a good point, but in my mind all of these changes come about because of the app. Suddenly you have a medium that allows you to do these things you couldn't before.
That's what I mean by facilitated. It wasn't having an app that made Uber successful, it was doing things that cabs couldn't. The app was just the means to the end.
I think there's a lot of "we need an app" thinking in the industry, but no thought as to what that app will do.
